【摘要】 计算机技术的发展促进了水轮机选型软件的研究与开发,然而由于计算机本身的限制,运转综合特性曲线的绘制始终是制约水轮机选型软件发展完善的关键因素。本文结合多年水轮机学习和软件开发经验,重点对混流式水轮机等效率线进行了研究,针对传统的绘制方法中存在的问题,提出了一种简便、精确的计算机绘制原型等效率线的新方法。更多还原

【Abstract】 The developments of the computer technology promote the study and the exploitation of hydraulic turbine type selection software,however,due to limitation of computer itself,Drawing of integrated operation characteristic curves is always the key that restricts the development and improvement of hydraulic turbine type selection software.This paper combines the learning of hydraulic turbine and the experiences of software development,especially studies on equal efficiency curve of francis turbine.Aiming at the problems in traditional drawing methods,this paper puts forward a simple and precise method of computer drawing prototype equal efficiency curve.更多还原
